#
# SYNOPSIS
#
#   AX_VALGRIND_CHECK()
#
# DESCRIPTION
#
#   Checks whether Valgrind is present and, if so, allows running `make
#   check` under a variety of Valgrind tools to check for memory and
#   threading errors.
#
#   Defines VALGRIND_CHECK_RULES which should be substituted in your
#   Makefile; and $enable_valgrind which can be used in subsequent configure
#   output. VALGRIND_ENABLED is defined and substituted, and corresponds to
#   the value of the --enable-valgrind option, which defaults to being
#   enabled if Valgrind is installed and disabled otherwise.
#
#   If unit tests are written using a shell script and automake's
#   LOG_COMPILER system, the $(VALGRIND) variable can be used within the
#   shell scripts to enable Valgrind, as described here:
#
#     https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html
#
#   Usage example:
#
#   configure.ac:
#
#     AX_VALGRIND_CHECK
#
#   Makefile.am:
#
#     @VALGRIND_CHECK_RULES@
#     VALGRIND_SUPPRESSIONS_FILES = my-project.supp
#     EXTRA_DIST = my-project.supp
#
#   This results in a "check-valgrind" rule being added to any Makefile.am
#   which includes "@VALGRIND_CHECK_RULES@" (assuming the module has been
#   configured with --enable-valgrind). Running `make check-valgrind` in
#   that directory will run the module's test suite (`make check`) once for
#   each of the available Valgrind tools (out of memcheck, helgrind, drd and
#   sgcheck), and will output results to test-suite-$toolname.log for each.
#   The target will succeed if there are zero errors and fail otherwise.
#
#   The macro supports running with and without libtool.
